To encourage students to read library books, small experimental kits were prepared on the basis of science books in library. Students checking out kits from library also check out appropriate books. Interest in reading has increased measurably. (PS)

Suggests using old tree stumps as a basis for arousing student interest and questions. (CP)

Illustrates the use of a flow chart to facilitate planning of laboratory exercises by two chemical examples. (AL)

A description of a popular chemistry course emphasizing the use of student teaching assistants, enrichment materials, and remedial aid. (CP)

Discusses the use of an integrated circuit operational amplifier in an introductory electronics laboratory course for undergraduate science majors. The advantages of this approach and the implications for scientific instrumentation are identified. Describes a number of experiments suitable for the undergraduate laboratory. (Author/DF)

Describes a program that attempts to bridge the gap between class lectures and laboratory. Students are involved in individual investigations. Effective use of undergraduates is made for instructional purposes. (PS)

A mixture of dough, using pancake flour, is used to represent the molten state of the earth billions of years ago. A simple experiment is designed to demonstrate that the earth's internal forces result from its unequal heating and cooling. Procedures are given to test this model with four theoretical hypotheses. (DF)

Describes two improvised models which can be used in classrooms to teach latitude concepts. Because of low costs involved, each student can be given the instruments involved in finding angles of elevations of different objects. (PS)

Describes a field project and associated activities used by the author with high school students in analyzing the Osage-type underfit stream. (PR)

Specific suggestions are given for activities which will interest young children and help them develop important skills basic to intellectual development. The emphasis is on involvement with materials as a method of learning." (Editor)
